Study Notes
Definition of Disaster
- A hazard becomes a disaster when it affects vulnerable populations, leading to destruction or harm.
- Natural events like volcanic eruptions or tsunamis must impact populated areas to be classified as disasters.
Characteristics of Disasters
- Disasters often occur unexpectedly, causing extensive casualties and property damage.
- They cannot be managed through conventional methods; rapid intervention from national agencies and NGOs is required.
- Disasters create demands that exceed local and national governmental capabilities.
Impacts of Disasters
- Medical Effects: Can include traumatic injuries, emotional distress, and the spread of diseases.
- Damage to Critical Facilities: Disasters can destroy vital infrastructure such as hospitals, communication systems, and water treatment facilities.
- Transportation Disruption: Roads and bridges may become impassable, hindering rescue efforts and emergency operations.
- Economic Impact: Business operations halt, and individuals must engage in disaster response activities instead of their regular jobs.
- Global Environmental Change: Evidence suggests that human actions and disasters contribute to climate change, escalating future risks.
- Social and Political Impact: Disasters expose existing inequalities, potentially prompting social and political transformations.
Concept of Disaster Risk
- Disaster risks can be quantitatively measured and provide comparisons between past and future incidents.
- The increasing encroachment on hazardous areas heightens disaster magnitude.
- Disaster risk is a function of hazard, exposure, and vulnerability, represented as:
- Disaster Risk = Hazard x Exposure x Vulnerability
Risk Assessment
- Evaluates potential impacts of hazards on people, services, and infrastructure.
- A risk map illustrates hazards, vulnerabilities, and expected damages.
- Key factors influencing disaster magnitude include severity of events, number of exposed individuals, and the quality of exposure.
Minimizing Disaster Risk
- Disaster risk can be mitigated by reducing exposure and vulnerability through preparedness measures.
- Relocation can be necessary but challenging due to people's attachment to their homes and livelihoods.
- Vulnerable populations often live in high-risk areas due to limited options and economic constraints.
- Awareness of risks is often undervalued as past disasters may create a false sense of security about future incidents.
Considerations for Relocation
- Effective relocation strategies should accompany other mitigation measures.
- Community resistance to relocation is common, especially when individuals must abandon productive land or homes.
- People may underestimate disaster risks based on misconceptions about the frequency of such events.
